Explaining low $$\ell $$ โ anomalies in the CMB power spectrum with resonant superstring excitations during inflation
We explore the possibility that both the suppression of the $$\ell = 2$$ multipole moment of the power spectrum of cosmic microwave background temperature fluctuations and the possible dip for $$\ell = 10$$ โ30 can be explained as well as a possible new dip for $$\ell \approx 60$$ as the โฆ
